Trembling Aspen is a hardy, fast-growing tree. It is known for its unique "trembling" leaf movement and beautiful bark that whitens with age.

This native shade tree tolerates a range of growing conditions and requires little maintenance.

Prairie Sky Poplar is a fast-growing columnar hybrid poplar developed at Agriculture and Agri-food Canada's Morden Research Station. It is adaptable to many soil conditions and seems to do best in the southern-most parts of the prairies.

Good as a shade or shelterbelt tree, it is often used in buffer zones as a visual screen or hedge. Ideal for lining properties, roads, etc.
